UV Light at the end of the Tunnel

Updated: Sep 13


Scientists have known the germicidal capability of UV light for decades. Will it be the catalyst untethering the Travel industry.



Ultraviolet light (UV, UVC) disinfection is a well-established technology for air, water, and surfaces treatments. Scientists have known for decades that germicidal UV light (wavelength around 254 nm) has the capacity to kill viruses and bacteria.


We all wish that the UV light could well be the light at the end of the tunnel and also grow to be a guiding path in eradicating the viruses and bacteria making aviation a much safer place for everyone.

In the last decade, UV technology found more applications in food production chain because this is economic, effective, and versatile dry processing technology that can potentially improve safety and preservation quality of different categories of foods.

The germicidal effects of UV LEDs against bacteria, viruses, and fungi already have been demonstrated and reported along with the first applications for disinfection of air, water, and surfaces made for the “point of use” integration. Hospitals and laboratories often use germicidal UV light to sterilize unoccupied rooms, as well as other equipment. But conventional germicidal UV light cannot be used in the presence of people as it can causes health problems to the skin and eyes.


In contrast, far-UVC light, which has a very short wavelength (in the range from about 205 to 230 nm), cannot reach or damage living human cells. But these wavelengths can still penetrate and kill very small viruses and bacteria floating in the air or on surfaces.


During this Pandemic the use of UV germicidal wavelength has come to the forefront and received lot of traction in the media. Many established companies have invested in the technological enhancement and also collaborated with Start-ups so as to quickly hit the market with solutions that are used in industries as well as households for domestic use.


As the World is trying to come to terms with this new way of life, aviation is also struggling to find ground and rise from the huge slump which it has never experienced earlier. All businesses within the aviation ecosystem, be it hotels, restaurants, car rentals, tourist places, aggregators have their eyes glued to the commencement of air travel. The dependency and the desire to succeed are so immense that UV-C could well be a game changer in bringing the passenger sentiment back into flying.


I am sure we all wish that the UV light could be the light at the end of the tunnel and also grow to be a guiding path in eradicating the viruses and bacteria making aviation a much safer place for everyone.
